Archaeopteryx possessed both _ and _ characters:
Correct answer: B. Reptilian, Avian
- A. Reptilian, Amphibian
- B. Reptilian, Avian
- C. Fish, Avian
- D. Mammalian, Avian
Explanation
Archaeopteryx is a critical fossil that provides evidence for evolution by illustrating the link between reptiles and birds. Dating back to the Late Jurassic period, around 150 million years ago, it exhibits a unique mix of features: reptilian traits such as a long bony tail, teeth, and claws, alongside avian traits like feathers and wings. This makes it a classic example of a transitional fossil. The incorrect options fail to represent this specific combination of reptilian and avian features accurately.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
